Autopage and Commando are the exact same products but labeled differently and they have different styles of key fobs. I love the 2way range on them. It's not two miles but it is all of three city blocks and that's enough for me.
The Crimstoppers I've used don't seem to have the range of the Autopage and the other remote "backup remote" is really cheaply made but that's model dependent and.. it's a backup remote right? Crimestopper is still a great alarm company and I trust them.
